Study Notes

Aging and Nutrition

  • Aging is a natural process that brings about various health changes.
  • Healthy lifestyle habits, like good nutrition and physical activity, can reduce disease risk and enhance life quality in older adults.

Energy Needs

  • After age 50, energy needs decrease by approximately 5% per decade.
  • Decreased metabolism, muscle mass, and physical activity contribute to reduced energy requirements.
  • Careful meal planning is crucial to meet nutrient needs while consuming fewer calories.

Weight Management

  • Generally, weight gain should be avoided, but a slight gain may be beneficial for those aged 70-75.
  • Studies indicate that lower death rates are observed in overweight individuals compared to those classified as obese.
  • BMI rankings may need adjustment for individuals over 65 to reflect changing health dynamics, though there's no universal standard.

Vitamin D and B12 Considerations

  • The skin's ability to synthesize vitamin D decreases with age, combined with typically reduced sun exposure among older adults.
  • Vitamin B12 needs are higher in older adults, although the recommended dietary intake remains unchanged.
  • The ability to absorb naturally occurring vitamin B12 diminishes with age; thus, synthetic forms of the vitamin are recommended for better absorption.
